IMPROVEMENT IN COMPOUND MACHINES FOR UPSETTING, PUNCHING, AND CUTTING'A METAL.

f The Schedule referred to in these Letters Patent and mking part of the same To all whom 'it may concern:

Be it known that I, WILLIAM HUNT, of 'Oskaloosa, in the county of Mahaska and Stat-e of Iowa, have invented a new and useful I mproyement-iuMachine for Upsetting W'agon-Tire and other purposes; and I do hereby declare-that the following is a full, clear, and exact description thereof,'which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvement 'in tire-upsetting machine, and consists in the upsetting mechanism, which includes a.punchdie, and cutters that are detachable, and interchangeable one with another, as hereinafter set forth.

' In the accompanying drawing- Figure l represents a sectional side elevation of the machine as applied to upsetting tire.

Figure 2 is a top view, showing a removable punch and die arranged on the machine for punching holes 1n iron.

Figure 3 is also a top view, showingr cutters arranged on the machine for cutting up small bars of iron for boltso'r other purpmes.v

Figure etv is a side view of fig. 3, partly in section.

Similar letters of reference indicate correspoiuling parts. v A is the bed-'plate, which supports'the entire apparatus. This bed may be made of either wood or metal, buta stiff -pieee of hard-wood plank is all that is required.

A is a iianged head, which is bolted orfastened to the hed in any substantial manner.

B is a-head of similar construction, which is movable, vor made to slide on the bed by means of the bar C, to which it is attached, las represented in iig. 4.

Each of the heads are recessed ont on their under sides to receive the bar C, so that the bar slides beneath the stationary head, whileth'e movable head rests and slides on the bed. f

l) represents vertical flanges, (two on each heath) through which are triangular or other shaped keyholes E.

The space between the iianges is designed to be sufficient for 'the width of the tire, (say two inches,

more or less,) and'thesc inner surfaces incline toward cach other, so as to corresnond in some manner with -O`is attached, as secu'at the pointH.

I is the fulcrnm of the lever. The tire being securely fastened to each head with a heated portion between the heads, it will 'be seen that, when'the lpowerful purchase obtained by the lever is brought to bearupon it', the heated portion must' he upset, 'and the tire made less in diameter than it was before. 1t will be observed that the point of resistance is on a level with the point of connection H, so that the power is'directly applied to the object in view.

J vand K represent a punch anddie, each with shanks, which rest between the flanges D, where they are fastened by the keys F. c

L and M are cutters, fastened to Vthe heads in the same manner, which operate -as. shears, to cnt small bars of iron, the movable head B being operated by the lever, the same for punching and cutting as for upsetting.

` N represents shoulders on the punch and die Vand on the cutters, which bear on the inner ends of the heads,'which prevents any back i'notiol'r when the 'power is applied.

- Having thus described my invention,

I claim as new and desire to secure by Letters Patent-V`v J ointly, the tire-upsetting mechanism, consisting of 'the base A, heads A' and 15, bar C, and lever G, and

the punch and die J K, and pair of cutters L M, said punch and die and cutters being separate and detachable,'applicable'to the upsetting device, and interchangcable'with'onc another, lall substantially as described.

Witnesses: WILLIAM HUNT.'
